I am using Outlook 365 1909 (Build 12026.20320) Monthly Channel. The Sun and Moon button was available in message's toolbar in Outlook for several days and now it is gone. No policies have been changed and system is restarted every evening. Microsoft Windows Version 1903 (18362.388) x64.

Thank you.

Hi all,

The Outlook Team currently has the Sun/Moon feature enabled in Monthly Channel Production at 10% of users.  It was enabled at a higher percent earlier until a bug was found.  The team wants to fix that bug before it gets turned back on for everyone.  If I can get an ETA on the rollout I'll post back with that status.

I experienced the same dark mode problem. May we know whether dark mode in outlook (with sun/moon button) is a beta feature or released feature?

If this is a released feature, why sun/moon feature is enabled in only 10% users ?

If this is in beta testing, why it is released in monthly production update?

    Following (keenly) to know when it will return. It is a GREAT feature, by the way - thank you very much!

    From what I can tell the Sun/Moon feature is enabled 100% for Monthly Channel.  If you click File, Office Account, under About Outlook what Build and Channel do you have?

    If you are on Semi Annual Channel there are steps documented here to switch to Monthly Channel, https://docs.microsoft.com/en-us/office365/troubleshoot/administration/switch-channel-for-office-365.  

    The earliest the feature would get to Semi Annual is likely July next year per channel updates page, https://docs.microsoft.com/en-us/DeployOffice/overview-of-update-channels-for-office-365-proplus.

    Excellent update, thank you Gabriel Bratton! I followed your guidelines and it worked like a charm, and I also learned something new about the semi-annual and monthly updates.
